This anomaly is truly fascinating. Anything brought within the active area containing any kind of complex information will see that information erased. I find it quite interesting that there seems to be a limit to what information it will consume: for example the many plants in the active zone seem to fine, even though I would have expected an anomaly targeting all information to destroy their genetic information. There is much research needed on the exact limits and target selection.

[redacted for brevity]

It disappeared! The anomaly vanished in seconds, with a flash of light and a loud thundering sound. The entire area has reverted to being non-anomalous, although there are numerous patches of plants that seems to have suffered something resembling acute radiation poisoning. My working hypothesis right now is that whatever limits there were to this anomaly, they suddenly ceased to be effective and it consumed all the available information to the point of self-destruction. Well, I guess this one will stay a mystery on the anomalous event log.

They found another one! It’s the exact same kind of information-eating anomaly as last time in █████. This time I even got the approval to send a D-class in the active area, which I hope will give us information on the speed and pattern of progression of the anomaly.

The experiment had… unexpected results. Much to my dismay it seems that the anomaly wiped her ability to talk first, and by the time we got around to try to get her to write something it seems like that was gone too. The interesting part is that I expected to pull a vegetable out of the active zone, but she seems to be much more functional than I would have thought, and she was able to pass some simple logic and coordination tests, like tying her shoelaces. But her ability to communicate seems to be completely and utterly gone, which makes a more complete assessment of the effects of the anomaly difficult: who knows what is really left of a human being in there? It could be anything from an almost fully-conscious mind trapped within itself to a barely conscious ghost of a person, not even aware of all the things that it cannot remember. To be honest both possibilities send chills down my spine.

Another one of those anomalies was tracked down. They never last long and manifest seemingly at random, but for now haven’t appeared anywhere populated. More to the point, with the few last tests establishing that sending more D-class just wields the same result I’ll be trying again with a few remotely monitored laptops.
The results were pretty interesting, and not what I had expected once again. While the first laptop seemed to get erased pretty haphazardly, suffering random and worsening malfunctions before crashing irrecoverably, the results for the second laptop were the interesting ones: the display got shutdown almost immediately, but the laptop itself kept running, and while parts of the disk did get erased, none of it was necessary for the continued function of the computer. More disturbing still, a lot of the targeted data belonged to caches and buffer that got recreated each time the computer noticed they were missing.

This changes a lot of things about what we thought of this anomaly, the most important and frightening of which being that it seems to have some kind of sentience and ability to learn, fast. But for now, there is only one thing that I can say for sure about this anomaly: further research is required.

The anomaly SCP-3432 keeps creating new questions, but from enough observation I think I finally have a few answers. It is obvious that SCP-3432-A instances are related, but rather than separate occurrences of a similar anomaly, I think that they have a common and unique cause. And from the results of the tests I conducted, I would go so far as to say that this common cause is some kind of sentient entity.

From the violent side effects of an SCP-3432-A dissipation event I hypothesize that the intrinsic nature of SCP-3432 is something fundamentally contrary to the concept of information, an equal and opposite of sorts that annihilate on direct contact. How could something like this be sentient then? My theory is that just as information can be manipulated, this “anti-information” (for lack of a better word) can too, and SCP-3432 is an anti-information based mind, existing someplace outside of our reality where the laws of our universe cannot contradict its existence.

Then, SCP-3432-A instances would be the equivalent of a dimensional spacesuit, something that helps it sustains its presence in our reality, enough to gradually erode information and not purely annihilate it. But that begs the question, why? Does SCP-3432 gains anything from the information it destroys? Is it exploring? Consuming? Impossible to tell for now, and it could even turn out to be something else entirely. Its interaction with human minds is most peculiar too: why does it mostly appear to destroy information linked to communication? Is it on purpose, or does it just not understand? As I have said, there might be some answers, but there are even more questions.

Regardless of what the final answers are, SCP-3432 still seems to have enough difficulties interacting with our reality to not be considered a major threat. But still, seeing how fast it seems to be able to learn and adapt, I would recommend for all tests regarding SCP-3432 to be suspended as a precaution.

Incident-3432-07: After a leak of GOC intelligence, the Foundation became aware of the existence of a GOC project apparently directed at developing a weaponized version of SCP-3432’s effect, based on an incomplete understanding of the anomaly. Foundation intelligence indicates the project to have been cancelled and thus not cause for direct concern, but action might be necessary if related projects were to be revived.
Senior Researcher Peterson’s note

Despite the official lack of concern, what the GOC accomplished is quite disconcerting. It appears that through the use of anomalous memetic triggers they were able to effectively causes the human mind to generate the same kind of “anti-information” that makes up SCP-3432. Even if their worry of the meme spreading was based on an incomprehension of the nature of SCP-3432-A, the fact that an operation exists that can generate “anti-information” from real information is alarming, because I don’t know what would happen if SCP-3432 itself were to learn of it.
